Next-generation energy-efficient and high-performance condensing boiler
January 20, 2024 2:52 pm
Riello, a division of Carrier Global Corporation, a global leader in intelligent climate and energy solutions, introduces the RESIDENCE HM condensing boiler, incorporating advanced technologies to enhance performance and energy efficiency.
This boiler, IoT-ready and 20% hydrogen-compatible, marks a significant upgrade. One key enhancement from the previous model is the implementation of a high 1:10 modulation ratio, reducing gas consumption and carbon emissions by minimising on/off cycles. A new energy-efficient digital circulator with EEI ≤0.20 has also been introduced. Riello’s latest ACC system ensures optimal combustion, maintaining consistent efficiency and emissions within regulatory limits by adapting to fuel type and flue length. Particularly in combi models, the RESIDENCE HM demonstrates impressive domestic hot water (DHW) performance, attributed to an upgraded DHW exchanger by Riello.
The modern residential boiler boasts a user-friendly interface with a new touchscreen and internet connectivity through its ‘Hi, Comfort’ digital platform, enabling comprehensive IoT networking. It also features an updated room control with advanced functions and a sleek design. Its integrated gateway manages up to three zones and operates as a system manager for hybrid installations, ensuring optimal energy use. Noise levels of the RESIDENCE HM start at 45 dB, a 10% reduction compared to its predecessor.
The technology prioritises environmental responsibility, extending the company’s legacy in sustainability. The RESIDENCE HM is compatible with hybrid systems and can function with natural gas blends and up to 20 percent hydrogen. Riello’s tests indicate potential compatibility even with 100 percent hydrogen, facilitated by the ongoing development of a conversion kit.

The boiler includes a fixing plate and DIN-type connections to ensure versatile installation. Simplified installation and maintenance are facilitated by the compact size (740 x 420 x 275mm) and lightweight construction, weighing between 28-30kg. No gas valve calibration is required because of the self-adaptive system that simplifies the initial ignition process.
